Sabotage directories?

What happened?!?!?

Recently, my company was moving up in rankings on SERPs. No solid PR change yet, but we’re waiting for Jan. At any rate, I’m doing a check of datacenter ranks and I see ‘not in top 100’ in the results, sporadically. We’ve been in top 100 for some time now with relevant info and such growing almost daily for the term ‘chicago real estate’. I checked toolbarqueries and two other pages come up in the SERP. We've also dropped off of MSN's top 100. Please check out the following link and share with me any ideas you may have. It doesn't 'feel' good to me, but I'd like some unbiased opinion and possible resolution ideas.

If it is a new site you might have been sandboxed, however if you are not ranking on MSN it is not a good sign you need loads of high PR sites linking to you using the phrase Chicago real estate in the text that links to your site.

We are not an old site. I'm asking if spam pages with our URL coded all over it may affect our rankings.

Let me offer more background:

1. To my knowledge, we are not linked to any bad sites.
2. Multiple copies of our homepage (i.e. /index, /home, etc...) have been addressed. Recognized pages (pages that rank well and have PR) have been perm redirect and those that weren't received a meta-robots 'none.' Could this be a reason?
3. The only recent optimizations have been to meta tags, primarily on interior pages.


If I could, I'd post the links so you could see what I'm talking about. It's a very odd situation and I've never heard of anything like this before, hence my reason for bugging you guys. To go from 'top 50' to 'not in top 100' is a painful drawback. Our SERP positions were slowly improving (site expansion, content additions, etc... all of which are very white hat) and suddenly, three pages (I believe recognized as blog pages) with our URL all over them, links to irrelevant sites, and a sex banner show up, and we get booted from top hundred on several G datacenters. I don't know how else to phrase it. Feel free to ask me for the URL's, but forum policy prevents me from posting them.

Thanks again, everyone!
